It looks like GoW II has the overall edge in graphics, but GoW and CoO are very close behind. Ready at Dawn did an excellent job with the PSP version.

Holy crap, T-Mac's eyes are going in different directions in the Live 08 shot. Meanwhile, Nash looks like a circus freak in NBA 08. And seriously, if I saw something that even remotely resembled NBA 08's version of Kaman coming at me, I'd scramble for a lead pipe. Yikes.
